State Pension Calculator UK
How this calculator works
For records entirely after April 2016, 35 qualifying years normally produce the full £241.30 weekly rate and at least 10 years are normally required. An entered official forecast overrides the simplified qualifying-year estimate because pre-2016 records, contracting-out and protected payments can change the result.
The State Pension Calculator provides an indicative estimate of the UK State Pension you may receive based on the qualifying National Insurance years entered. It can show a weekly, four-weekly or annual equivalent, but it cannot reproduce the Department for Work and Pensions calculation for every National Insurance history.
The full new State Pension is £241.30 per week for 2026/27. Your actual entitlement may be lower or, in limited circumstances, higher because of your contribution record, periods of contracting out, Additional State Pension, inherited amounts or deferral.
How does the State Pension Calculator work?
The calculator estimates a pension amount by comparing the qualifying years entered with the years normally required for the full new State Pension. Transitional National Insurance records may require a more detailed official calculation.
Enter the information requested by the calculator, such as your qualifying National Insurance years. The result applies the relevant 2026/27 State Pension rate and converts the estimated weekly entitlement into other payment periods where those outputs are provided.
For someone whose National Insurance record began after 5 April 2016, the simplified new State Pension calculation is:
Full weekly new State Pension × qualifying years ÷ 35
This simplified calculation is capped at the full standard rate and normally requires at least 10 qualifying years before any new State Pension is payable. Years do not have to be consecutive.
The calculation may not be reliable if your National Insurance record began before 6 April 2016. In those cases, the Department for Work and Pensions uses transitional rules and a starting amount based on the old and new State Pension systems.
What are the State Pension rates for 2026/27?
The full new State Pension is £241.30 per week for 2026/27, while the full basic State Pension is £184.90 per week. Which system applies depends principally on when you reached State Pension age.
| State Pension rate | Weekly amount for 2026/27 | Who it generally applies to |
|---|---|---|
| Full new State Pension | £241.30 | People who reached State Pension age on or after 6 April 2016 |
| Full basic State Pension | £184.90 | People who reached State Pension age before 6 April 2016 |
These are full standard rates rather than guaranteed individual payments. The Department for Work and Pensions publishes the confirmed benefit and pension rates for 2026/27.
The basic State Pension belongs to the system applying to people who reached State Pension age before 6 April 2016. Their total payment may also include Additional State Pension, Graduated Retirement Benefit, inherited amounts or a deferral increase, so multiplying qualifying years by the basic rate may not produce the correct result.
Illustrative State Pension calculation
This illustrative example uses the simplified rules for a person whose National Insurance record began after April 2016. It does not account for transitional rules, contracting out, future uprating or changes in legislation.
Illustrative assumptions: the person has 30 qualifying years, needs 35 years for the full new State Pension and is being assessed using the 2026/27 full weekly rate of £241.30.
| Calculation step | Illustrative amount |
|---|---|
| Full weekly rate | £241.30 |
| Qualifying years | 30 |
| Fraction of full pension | 30 ÷ 35 |
| Estimated weekly pension | £206.83 |
| Estimated four-weekly pension | £827.32 |
| Estimated annual equivalent | £10,755.16 |
The weekly estimate is calculated as £241.30 multiplied by 30 and divided by 35. The annual equivalent uses 52 weeks, while actual State Pension payments are usually made every four weeks.
Under this simplified example, one further qualifying year would add approximately £6.89 per week at the 2026/27 rate. An additional year will not increase someone’s pension if they have already reached their applicable maximum or if their individual record prevents the year from improving their forecast.
How many qualifying years are needed for the State Pension?
People with no National Insurance record before 6 April 2016 normally need at least 10 qualifying years for any new State Pension and 35 for the full standard amount. Different results can apply where the record includes earlier years.
A qualifying year can arise through paid or treated-as-paid National Insurance contributions, National Insurance credits, self-employment or voluntary contributions. A year may qualify even when no employee National Insurance is deducted, provided earnings meet the relevant conditions.
National Insurance credits may be available during periods involving certain benefits, unemployment, illness or caring responsibilities. For example, registering for Child Benefit for a child under 12 can protect the claimant’s National Insurance record even if they choose not to receive the payments.
Having 35 qualifying years does not guarantee the full new State Pension when the record includes years before 6 April 2016. Contracting out and the transitional starting-amount calculation can alter how many further years will improve the entitlement.
How do pre-2016 National Insurance years affect the estimate?
For records extending before 6 April 2016, the new State Pension began with a transitional starting amount. This means entitlement cannot always be calculated by dividing qualifying years by 35.
The starting amount was broadly the higher of what the person had built under the previous State Pension system and what they would have built under the new system to 5 April 2016. Both calculations took relevant contracting-out periods into account.
Someone who was contracted out may have paid lower National Insurance while pension provision was made through a workplace or personal pension. Their State Pension starting amount may consequently have been below the full new State Pension, although qualifying years after 5 April 2016 can sometimes increase it.
Some people had a starting amount above the full new State Pension because of Additional State Pension accrued under the previous system. The excess is generally treated as a protected payment and can mean their entitlement is higher than the standard full rate.
GOV.UK provides a detailed explanation of how the new State Pension and starting amount work.
When can the State Pension be claimed?
The State Pension becomes claimable at your individual State Pension age, which depends on your date of birth and legislation. It is not paid automatically merely because that age has been reached.
State Pension age is currently 66 and is being increased to 67 between 2026 and 2028 under enacted legislation. Later increases are also legislated, but the timetable can be reviewed by the government.
A calculator estimate of the payment amount should not be used to determine the exact date on which you become eligible. Use the official State Pension age service for your personal date.
You normally need to claim the State Pension. If you do not claim when you reach State Pension age, it is generally treated as deferred.
What happens if the State Pension is deferred?
Deferring the new State Pension can increase future weekly payments, but it means giving up payments during the deferral period. Whether this is beneficial depends on factors the calculator cannot fully assess.
For people reaching State Pension age on or after 6 April 2016, the new State Pension generally increases by 1% for every nine weeks of qualifying deferral. This is just under 5.8% for a full 52-week period.
Deferral may be less suitable where life expectancy is shorter, income is needed immediately or additional pension would reduce entitlement to means-tested benefits. Tax can also affect the value of the increased payments.
Different deferral rules apply to people who reached State Pension age before 6 April 2016. The official State Pension deferral guidance should therefore be checked before relying on an estimate.
Is the State Pension taxable?
The State Pension is taxable income, although it is normally paid without tax being deducted. Whether tax is ultimately due depends on your total taxable income and available Personal Allowance.
Your State Pension is added to private pensions, employment income and other taxable income when determining your Income Tax liability. If you receive a private or workplace pension, HMRC may collect tax attributable to the State Pension by adjusting the PAYE tax code used by that provider.
National Insurance is not charged on State Pension income. Reaching State Pension age also generally ends employee National Insurance liability on employment earnings, although employers may continue to pay employer National Insurance.
The Income Tax Calculator can provide additional context for pension and other income, but it does not replace an HMRC calculation based on your complete circumstances.
Can gaps in a National Insurance record be filled?
Some gaps can be filled through voluntary National Insurance contributions, but paying for a missing year does not always increase the State Pension. Check the official forecast and contribution record before making a payment.
Voluntary Class 3 contributions are £18.40 per week for 2026/27. Lower voluntary Class 2 rates may apply to certain eligible self-employed people. The amount required to fill an earlier year can depend on that year and when payment is made.
You can usually pay voluntary contributions for gaps within the previous six tax years, subject to deadlines and exceptions. Before paying, confirm that the year is incomplete, can still be filled and will increase your individual State Pension entitlement.
Use the National Insurance Calculator to estimate current contributions from earnings. It does not determine whether a historical gap should be filled.
Important limitations of the State Pension estimate
The calculator cannot access your official National Insurance record or reproduce every transitional and inherited entitlement rule. Your GOV.UK State Pension forecast is the more reliable source for your personal amount.
- Qualifying years entered by the user are not verified against HMRC records.
- Pre-2016 contributions and periods of contracting out may change the result.
- The estimate may not include Additional State Pension, protected payments or inherited entitlement.
- Home Responsibilities Protection and National Insurance credits may require correction or confirmation.
- Overseas contributions and time spent living or working abroad can involve different rules.
- Future State Pension rates cannot be guaranteed from the 2026/27 amount.
- The calculator does not confirm your exact State Pension age or claim date.
- Tax, Pension Credit and other benefit interactions require separate assessment.
Check your official State Pension forecast to see the amount you could receive, when you can receive it and whether further qualifying years may improve it.
This calculator provides estimates only. Actual State Pension entitlement, National Insurance records, personal circumstances and available credits or reliefs differ, and pension or tax rules may change; appropriate professional advice may be suitable where the record or tax position is complex.
